[jira] Created: (TRINIDAD-95) Incorrect handling of transient components when JSF1.2 is used

Incorrect handling of transient components when JSF1.2 is used
--------------------------------------------------------------

                 Key: TRINIDAD-95
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-95
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 1.2.1-core
         Environment: Facelets 1.1.11, jsf 1.2 RI or myfaces 1.2-SNAPSHOT
            Reporter: Leszek Kowalski


When jsf1.2 is used with token state saving (javax.faces.STATE_SAVING_METHOD=client, org.apache.myfaces.trinidad.CLIENT_STATE_METHOD=token) transient components are not removed from the tree after rendering.
This causes problem with facelets - multiple rendering of transient content. Clicking redisplay button in following
example will cause facelets to display "test" two times. It happens because facelets expect that jsf 1.2 implementation will remove
transient components from the tree.

from FaceletViewHandler.java:
            // remove transients for older versions
            if (FacesAPI.getVersion() < 12) {
                ComponentSupport.removeTransient(viewToRender);
            }
